The complete molecule of the title compound, C22H24N2O6, is generated by crystallographic inversion symmetry and is approximately planar (r.m.s. deviation of the non-H atoms = 0.134 Å). The packing consists of inter-digitated sheets inclined at 25.9 (4)° to one another and linked by short C—H⋯O hydrogen bonds.
Keywords: crystal structure; azomethenes; bis-phenoxy carboxylate.

A mixture of 1 mmol (326 mg) of ethyl (2-{(Z)-[(2E)-(2-hydroxybenzylidene)hydrazono]methyl}phenoxy)acetate and 1 mmol (167 mg) of ethyl bromoacetate in 30 ml of ethanol was heated under reflux for 24 h. The resulting solid product was filtered off, dried and recrystallized from dichlomethane solution to furnish pale yellow blocks in 90% yield (m.p. 383 K).
H-atoms were placed in calculated positions (C—H = 0.95 - 0.98 Å) and included as riding contributions with isotropic displacement parameters 1.2 - 1.5 times those of the attached carbon atoms.
Imines are used as catalysts, in medicine as antibiotics and anti-inflammatory agents and in industry as anticorrosion agents (Sun et al., 2001; Boghaei & Mohebi, 2002; Liu et al., 2006; Britovsek et al., 2001; Budakoti et al., 2006). Based on these finding we report here the synthesis and
of the title compound.The title molecule has crystallographically imposed centrosymmetry with an "extended" conformation in which the central portion is almost planar. Intermolecular C6—H6···O2 hydrogen bonds (Table 1) assemble the molecules into interpenetrating sheets which are inclined to (100) by 24.0 and 24.3° and to one another by 25.9° (Figs. 2 and 3).

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes. |
Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger. H-atoms were placed in calculated positions (C—H = 0.95 - 0.98 Å) and included as riding contributions with isotropic displacement parameters 1.2 - 1.5 times those of the attached carbon atoms. |

Imines are used as catalysts, in medicine as antibiotics and anti-inflammatory agents and in industry as anticorrosion agents (Sun et al., 2001; Boghaei & Mohebi, 2002; Liu et al., 2006; Britovsek et al., 2001; Budakoti et al., 2006). Based on these finding we report here the synthesis and crystal structure of the title compound.
The title molecule has crystallographically imposed centrosymmetry with an "extended" conformation in which the central portion is almost planar. Intermolecular C6—H6···O2 hydrogen bonds (Table 1) assemble the molecules into interpenetrating sheets which are inclined to (100) by 24.0 and 24.3° and to one another by 25.9° (Figs. 2 and 3).
